Complete disaster - ODIN Works Creedmoor Complete Upper Reciever

Ill try to make a long story short. Bought a 6mm creedmoor upper. Received a 6.5 creedmoor upper. Box was labeled 6mm. I ordered a 6mm. Didnt bother to look at barrel stamp. Took it out to shoot. Bullets were hitting paper sideways. Look at barrel stamp and it was a 6.5 creedmoor. Obviously not good. Wrote Odin about it and they wanted it returned. Ok. First problem. Sent me a 6mm creedmoor this time. It bulged factory brass so bad that im surprised it didnt blow cases up. Wrote them about that. They offered me a store credit because they werent offering 6mm creedmoor uppers anymore. No offer to fix it. Ive ruined $100s on brass now trying to get it to work. Checked throat with OAL gauge..its severly short throated and I'm guessing flawed chamber for brass to be bulging in same place on one side of case. Im not a smith so I cant say that 100%. Now I have to buy another barrel and they are hard to find for under $500. Bad experience. I'll never buy anything from Odin Works again.
